COVID-19 guidelines have simplified significantly since the pandemic’s early years. The CDC now treats COVID similarly to other respiratory viruses like the flu, with one core rule for returning to normal life: stay home until you’ve been fever-free for at least 24 hours (without fever-reducing medication) and your symptoms are improving overall.
When to Stay Home and When to Go Back
The current CDC guidance applies to COVID, flu, and other respiratory viruses equally. If you’re sick, stay home and away from others. You can return to work, school, or other normal activities when two things have been true for at least 24 hours: your symptoms are getting better, and you haven’t had a fever without using medication like ibuprofen or acetaminophen to control it.
If you go back to your routine and then develop a fever again or start feeling worse, the CDC recommends staying home once more. You restart the 24-hour clock: wait until symptoms are improving and you’ve been fever-free for a full day before resuming activities. There is no longer a fixed 5-day or 10-day isolation window like earlier in the pandemic.
Testing After Exposure or Symptoms
If you have symptoms and want to confirm whether it’s COVID, a rapid antigen test (the kind you take at home) is a reasonable first step. But a single negative rapid test isn’t always reliable. The FDA recommends two negative antigen tests taken 48 hours apart if you have symptoms. If you don’t have symptoms but were exposed, three negative tests spaced 48 hours apart provides more confidence.
PCR tests (also called nucleic acid amplification tests) remain the most accurate option and are more likely to catch the virus than rapid antigen tests. These are typically available at clinics, pharmacies, or testing sites and are worth pursuing if you’re getting negative rapid results but still feel sick. Keep in mind that PCR tests can stay positive for weeks after infection, so they’re most useful early on rather than for confirming you’ve recovered.
Vaccines for 2025
The CDC recommends COVID vaccination for everyone ages 6 months and older. The current approach is individualized: the number of doses you need (typically one or two) depends on your age and whether you’ve been vaccinated before. Updated vaccines are formulated to match circulating strains, similar to how the annual flu shot works.
For people who are immunocompromised, the recommended schedule may include additional doses, though the specifics depend on your medical situation. If you fall into this category, your doctor can determine the right number and timing of doses based on your immune status.
Masking Is Optional but Strategic
There are no general mask mandates in public settings. The CDC frames masking as one tool among many, particularly useful in specific situations: when respiratory illness is surging in your community, when you’ve recently been exposed to someone who’s sick, when you’re recovering from an illness yourself, or when you or people around you are at higher risk for severe illness.
Crowded indoor spaces during periods of high transmission are the scenarios where masks make the most practical difference. Healthcare facilities may have their own separate masking policies that go beyond general community guidance, so check with the specific facility if you’re heading to a hospital or clinic.
Antiviral Treatment for High-Risk Groups
Prescription antiviral treatment for COVID is available for adults and for adolescents over 12 who weigh at least 88 pounds (40 kg). To qualify, you need to have one or more risk factors for developing severe illness. The specific list of qualifying conditions is broad and includes things like obesity, diabetes, heart disease, lung conditions, and being over 65, but the decision ultimately comes down to your doctor’s assessment of your individual risk.
Timing matters with antivirals. They work best when started within the first few days of symptoms, so if you test positive and think you might qualify, contact your healthcare provider quickly rather than waiting to see if you get worse.
Long COVID Still Affects Some People
Long COVID is defined as a chronic condition that lasts at least three months after a COVID infection. It’s not a single illness but rather an umbrella term for a range of ongoing symptoms, from fatigue and brain fog to heart palpitations and joint pain. There is no lab test that can confirm or rule out long COVID. A positive COVID test isn’t even required for diagnosis.
Doctors diagnose long COVID based on your health history, whether you had a confirmed or suspected COVID infection, and a physical examination. If you’re still experiencing symptoms months after an infection, that pattern itself is what points toward the diagnosis. Treatment focuses on managing individual symptoms since there’s no single therapy that addresses all forms of long COVID.
